MECHANICAL HORN.

To all whom it may concern:

Be it known that I, EMANUEL AUFIERO, a citizen of the United States, residing at. Brooklyn, inthe county of Kings and State of New York, have invented new and useful Improvements in Mechanical Horns, of which the following is a,complete specificalion i V V The invention relates to a signal for automobiles, motorcycles and other vehicles; the mainobjeet thereof being the construction of signal device easily operated.

In the accompanying drawing, Figure 1, is a partly sectional view of one embodiment of the invention; Fig. 2 is a front view of same.

Similar numbers refer to similar parts. in

piece of cast or rolled material.

An approximately cylindrical easing 1, made preferably of sheet steel drawn to shape, is provided with a flange at right angle thereto having a rim 19 adapted to in close the corresponding flange 20 at the end of the resonating chamber 2. The vibratory metallic plate 3 is clamped th'crebetween, the parts being held together by screws or otherwise.

At two diametrically opposite points of casing 1,- two adjustable bearings 21 and 22 are provided for a cross-shaft formed with a pinion 6, which moves alternately forwardand backward by means of the toothed part 5 fastened to piston 4 which moves in "twoopposite openings 11 and 11 located on the same easing; the piston being moved downward by the operator and the compression spring 18 returning it to normal.

To said pinion is rigidly fastened the driving ratchet 7 which engages the driving pawl to the freely revolving lly-wheel 1G and diaphragm actuator .9; the spring 10 similarly supported pressing the above named pawl in operative engagement with the ratchet 7.

It is very desirable. that the fly-wheel 16 shall be made of relatively thin steel laminations; six laminations about in thickness, as shown at 15, may be provided. This construction avoids the undesirable. uneven distribution of weight through .lhe mass of the fly-wheel that occurs when a lly-wlieel of the same size and material is made of one The diaphragm is vibrated by the actuator 5). through the wearpiere 'l-l in engagement therewith. A stud 12 is provided for said Specification of Letters Patent.

wcarpiece having a shoulder 25 of smaller diameter than the diameter of washer 13 on which said stud is riveted. It is found in practice that this arrangement will prevent a fracture of the diaphragm near. the clamped edge of the wear-piece supporting members.

In horns of this character the cheapness .of construction and simplicity of operation are of prime importance. By the above described construction I obtain a direct ap-' plication of power to the serrated disk without intermediate gearing of any kind. The elimination of the intermediate gearin permits the serrated disk to occupy the fufi parti g from the scope of the claims.

Wnat I claim is:

1..In a mechanical horn, the combination of a vibratory diaphragm, a casing having one end closed by said diaphragm, a shaft supported iii-said easing with its axis parallel to the ,plane of said diaphragm, a pinion on said shaft, a heavily weighted serrated disk having operative connection with said diaphragm mounted upon said shaft and rotatable independently of said pinion, a one-way clutch connection for transmitting motion from said pinion to said disk and a rack mounted for reciprocation in the wall of said casing and having operating eugagenwnt with said pinion.

2. In a. mechanical born, the combination of a resonating chamber, a casing secured to saidchamber, a vibratory diaphragm mounted between said chamber and easing, a shaft mounted for rotation in said casing having its axis parallel to the plane of said diaphragm.- a pinion on saidshaft, a heavily weighted disk having peripheral serrations freely mounted on said shaft, a wear piece carried by'said diaphragm and engaging said serrations, a pawl and ratchet connection between said disk and shaft and a manually operalable rack engaging said pinion and supported in said casing for recipro- Patented Sept. 4, 1917. 7 Application filed July 23, 1914.

v dimensions of the casing, and also permits ca! we: movementiu a plane parallel to said diaphragm and at right angles to said shaft.

3. In a mechanical horn, the combination of a vibratory diaphragm, a cylindrical casing, having one end closed by said diaphragm, a shaft supported in said casing with its axis parallel to the plane of said diaphragm, a pinion on said shaft, a disk provided with peripheral serrations freely mounted on said shaft, an annular Weight of an outside diameter substantially equal to the solid portion of said disk attached to said disk, a wear piece mounted in said diaphragm and engaging said serrations, a pawl and ratchet connection between said disk and shaft and a manually operatable rack mounted for reciprocation in said casing and engaging said pinion.

4. In a mechanical horn, the combination of a vibratory diaphragm, a casing having one end closed by said diaphragm, a Weighted serrated disk supported within said casing for rotation about an axis parallel with the plane of said diaphragm, a pinion supported within said casing adjacent said disk for rotation about the same axis, a one way clutch connection for trans mitting motion from said pinion to said disk and a reciprocating rack supported with its teeth in engagement with said pinion, said rack projecting beyond said casing to facilitate its operation.
